<p>Lombok为Java语言添加了非常有趣的附加功能，你可以不用再为实体类手写getter,setter等方法，通过一个注解即可拥有。</p>

<p>注意：需要安装idea的Lombok插件，并在项目中的pom文件中添加依赖。</p>

<p>用于解决用户下单以后，订单超时如何取消订单的问题。</p>
</blockquote>
<ul>
<li>用户进行下单操作（会有锁定商品库存、使用优惠券、积分一系列的操作）；</li>
<li>生成订单，获取订单的id；</li>
<li>获取到设置的订单超时时间（假设设置的为60分钟不支付取消订单）；</li>
<li>按订单超时时间发送一个延迟消息给RabbitMQ，让它在订单超时后触发取消订单的操作；</li>
<li>如果用户没有支付，进行取消订单操作（释放锁定商品库存、返还优惠券、返回积分一系列操作）。</li>
